When using this function purely for the benefit of affecting the TextDraw box, multiply 'Y' by 0.135 to convert to TextDrawTextSize-like measurements

Tips

If you want to change the letter size of a textdraw that is already shown, you don't have to recreate it. Simply use TextDrawShowForPlayer/TextDrawShowForAll after modifying the textdraw and the change will be visible.

Fonts appear to look the best with an X to Y ratio of 1 to 4 (e.g. if x is 0.5 then y should be 2).
